dsound enumeration patch
Robert Reif
reif at earthlink.net
Tue Jul 20 21:00:40 CDT 2004
It seems that TraktorDJStudio2Demo.exe expects device
GUIDs obtained from enumeration to be persistent. This
doesn't fix the device enumeration problem yet but it is a
step in the right direction.
Save enumerated GUIDs in a global array so they persist
after enumeration.
White space cleanup.
Add tests for opening default devices.
